A popular method Oral fluid testing has become a popular method for detecting the presence of drugs and its metabolites due to the speed of sample collection and ease of use. This is especially the case when testing in challenging environments such as the roadside, where collecting urine and other traditional specimens for preliminary screening is not practical. THE SOTOXA™ MOBILE TEST SYSTEM WA S P R E V I O U S LY K N O W N A S T H E D D S ®2 M O B I L E T E S T S Y S T E M The system is referred to as the DDS®2 Mobile Test System throughout the publications within this brochure.

Drugged driving in Wisconsin: Oral fluid versus blood OVERVIEW Dane County, Wisconsin launched a pilot project in order to evaluate the frequency of individuals driving under the influence of drugs. In the state of Wisconsin, drug testing is often cancelled if the blood alcohol concentration is above the specified limit set by the state. This resulted in around 3,600 drug samples being cancelled between December 2015 and July 2016. • Around 68 % of those samples that tested positive for drugs in this pilot study, would have previously been excluded as alcohol was above the specified limit....

Oral fluid roadside analysis pilot program Michigan law states that a person cannot operate a vehicle while under the influence of alcoholic liquor, a controlled substance, other intoxicating substance or a combination of these elements (Legislature Service Bureau, 2019). Over the last ten years in Michigan, drug-impaired driving has become more prevalent, and traffic fatalities have increased. • Out of all the tests conducted, 21 returned positive results for the presence of two or more drugs. During an evaluation of oral fluid as matrix for drug detection, the Oral Fluid Roadside Analysis...

Roadside drug testing: An evaluation of the DDS®2 Mobile Test System OVERVIEW Driving under the influence of drugs has increased over recent years and with the legalisation of cannabis in several US states, it is vital to monitor drug use whilst driving. • Out of 528 tests via the DDS®2 Mobile Analyser that were performed, only four tests were shown to be invalid by the DDS®2 system, which could be caused by factors such as insufficient sample volume. Oral fluid screening tests have become increasingly popular as a means of testing drivers for drugs at the roadside. Samples can be easily...

DDS®2 Mobile Analyser assessment In 2015 Victorian Institute of Forensic Medicine (VIFM) evaluated the DDS®2 Mobile Test System (now renamed the SoToxa™ Mobile Test System) in a laboratory environment. • During testing of negative samples, it was found that no false positive results occurred for any of the six drug groups being evaluated. The study was set out to evaluate the performance of the DDS®2 system for the 6-panel offering which included AMP, BZO, COC, MAMP, THC, OPI. • Testing at -50% of the manufacturer’s cutoff yielded no false positive results for AMP, BZO, THC or OPI. However,...

Prevalence of drug use among drivers based on mandatory, random tests in a roadside survey OVERVIEW Several studies have described the increase of drivers driving under the influence of drugs. In Spain, legislation prohibits driving under the influence of narcotic and psychotropic, stimulants, and other substances. In addition to those mentioned above, this also includes medicines which can impair the physical or mental skills of drivers. • The prevalence of driving under the influence of drugs in this study was around 16.4%. The authors in this study set out to evaluate the prevalence of...

An assessment of oral fluid drug screening devices OVERVIEW Since 2008, Canadian police have been authorised to perform a mandatory field sobriety test, evaluate individuals by a DRE, and request blood samples from drivers. • The length of time for the analysis of the test once the sample was collected: However, with limited availability of DREs and lengthy delays during the examinations, requests were made for an onsite screening device for use at the roadside. As such the authors of this study evaluated the performance of three of the most prevalent on-screen drug testing devices on the...

Evaluation of oral fluid as a specimen for driving under the influence of drugs Due to the legalisation of cannabis in some states of the United States, the number of drivers driving under the influence of drugs has increased. • The authors did not report any significant differences between the onsite screen using the DDS®2 system and the laboratory screen using ELISA. This study was set out to evaluate the effectiveness of oral fluid as a sample type for the use of drug detection in DUID cases. • The accuracy of the DDS®2 system was reported as: Drivers suspected of driving under the...

User experience and operational feasibility of four point-of-collection oral fluid drug testing devices according to Brazilian traffic agents OVERVIEW In Brazil it is estimated that around 43,000 people die annually in traffic collisions of which some of these are contributed to the presence of psychoactive substances. • 164 samples were collected over the four difference point-of-collection devices. Whilst Brazil has a zero tolerance for alcohol whilst driving and police regularly use breathalysers, there are no devices approved for drug testing on the roadside. The authors of this article...
